Nigeria's president, Muhammadu Buhari, has been meeting more than 100 girls after their dramatic release this week by Boko Haram, a month after they were abducted from their boarding school dormitories in the town of Dapchi in the northeast.

Zimbabwe's leading opposition politician, Morgan Tsvangirai, who was the arch political rival of ex-President Robert Mugabe, has died in a hospital in South Africa. He was 65 and had colon cancer.

Tsvangirai (pronounced chan-ghee-RYE) came to symbolize courageous resistance to Mugabe's repressive regime — and changed politics in Zimbabwe. As hard as he tried, he never managed to oust Mugabe at the ballot box. But the charismatic mineworker and labor union leader turned politician, and founder in 1999 of the opposition Movement for Democratic Change, came close.

Baptist Pastor Evan Mawarire is something of a cult figure in Zimbabwe. He's known for proudly wearing his country's national red, yellow, green, black and white flag around his neck. And Mawarire has deftly used social media to push his #ThisFlag hashtag campaign seeking social justice and constitutional rights, for which he's been hounded by security forces and jailed in the past.

"The Crocodile," "The Enforcer," "The Bodyguard," "The Spymaster." Those are just some of the names Zimbabwe's new leader goes by.

One could also add "The Survivor."

The nicknames are an indication of what Zimbabweans can expect of Emmerson Mnangagwa, who is 75, and poised to be sworn in as president to replace his one-time mentor Robert Mugabe, on Nov. 24.

As a young 18-year-old recruit to the independence liberation struggle, Mnangagwa was condemned to die by the Rhodesian authorities the guerrilla warriors — combatants and strategists — were trying to depose.

Robert Mugabe resigned as Zimbabwe's president today. It brings an end to his 37-year leadership of a nation he helped birth. His announcement was read out by the speaker of Parliament at the start of proceedings aimed at impeaching him.

Zimbabwe seems to be in the middle of a strange political transition. The country's military has seized power from longtime President Robert Mugabe. It looks in a lot of ways like a coup, but it has been pretty orderly.

Ingenuity, inspiration, an elaborate ruse and a touch of madness. That is what it took for Zainabu Hamayaji to protect her family from Boko Haram.

The terror network in northeastern Nigeria has killed 20,000 people, abducted thousands more and driven more than 2 million people from their homes during its eight-year insurgency. The 47-year-old mother of 10 — four biological and six orphaned children ranging from age 5 to 15 — had to feign insanity to keep the insurgents away.

Salamatu Umar was abducted by Boko Haram in 2014, when she was just 15. She and five other girls were herded in the bush. She was forced to marry a Boko Haram fighter.

She and another girl eventually escaped, running away while they were collecting firewood for cooking. Umar was pregnant at the time.

Today, she is 18 and the mother of a 1-year-old son, Usman Abubakar. She survived her "hell" and lives in a displaced people's camp in Maiduguri, the main city in northeastern Nigeria and birthplace of Boko Haram.

In 2014, Boko Haram seized the town of Gwoza in northeast Nigeria, killing hundreds of people. The insurgents declared that Gwoza would be the seat of their self-proclaimed caliphate. It was a perfect place for them, protected by a mountainside, with caves and tunnels for hiding out.
